Perfect Binary Tree

Famous quotes containing the words perfect and/or tree:

    We say justly that the weak person is flat, for, like all flat substances, he does not stand in the direction of his strength, that is, on his edge, but affords a convenient surface to put upon. He slides all the way through life.... But the brave man is a perfect sphere, which cannot fall on its flat side and is equally strong every way.
    Henry David Thoreau (1817–1862)

    As a natural process, of the same character as the development of a tree from its seed, or of a fowl from its egg, evolution excludes creation and all other kinds of supernatural intervention.
    Thomas Henry Huxley (1825–95)
